To all whom it may concern:

Be it known that I, QARLG. GUSTAFSONi, citizen of the. United States,-residing at Sioux City, in the county of WVoodbury and State of Iowa,have invented certain new and useful Improvements in Angle-Cocks, ofwhich the following is a specification.

This invention relates to angle cocks for train-pipes, andhas for itsobject the provision of an angle cock which may be operated from eitherside of the car and which will be so constructed as to avoid theliability of freezing; r The invention will be hereinafter fullydescribed and its novel features subsequently pointed out in the claimfollowing the description. I I

In the accompanying drawings which fully illustrate the invention;Figure 1 is a rear elevation of the angle cock, the operating handlebeing removed; Fig.2 is a front elevation of the same, the plug and capfor closing the plugchamber being removed; Fig. 3 is a side elevation ofthe angle cock; Fig. 4 is a vertical transverse section; Fig. 5 is avertical longitudinal section of the angle cock showing all the partsassembled; Fig. 76 is a rear elevation with the handle in position;1Fig,. 7 is a detail view of the latch mounted inthe han dle; Fig. 8 isa detail end view of the handle.

My improved angle cock, 3', is secured directly on the end of the trainpipe by a threaded connection, as indicated at 4, and a hose 5 isconnected to the end of the angle cock opposite the train-pipe to extendto the train-pipe coupling, as will be readily un'- derstood.

The angle cockconsists of a bodyhaving anupper arm 6 which is threadedonto the end of the train-pipe, the main body of the cock depending fromthe said upper arm 6 and therlower entremity of the body being turnedata slight angle to form the annulus 7 to which the hosecoupling 8 is?fitted. The

angle cock is bored throughout its length to provide a passage for thefluid and in the wedge it firmly in place. The plug, it, has" a conicalbody adapted to seat Within the said bushing and turn therein and hasone end extended, as indicated at 12, to project through the side oftliebody of the cock and have a handle secured thereto. A centraldiametrical passage or port 13fis formed through the plug so that, ifthe plug be turned to a position in which theport will register with theopenings 10 in the bushing, the flow through the cock will beuninterrupted and the air or steam may pass therethrough tothe coupling,while, if the plug .be turned to l a position in which the port l3, willextend across the plane of the openings 1 0 a t a rightiangle thereto,the flow will be cut off and the train-pipes may be vuiicoupledwithoutany appreciable loss of s teain'sor a'irl On the side of thebody, immediately adjacent the larger end of l the bushing se'at, is,,for11ie'd an external collar l-it' which is internally threaded, to been-' Patented his,

l Th .p ee insend 1 the l ke i .a -i

e ilai a shbimmostx leafly i Fi -[61. nd is a sbs onsfi ue edsi th irib2 s thaten angular engagement between the plug and the handle 23 Will be,efi'ected when the upper end of the handle, which is provided with asimilarly shaped transverse opening, is engaged over the end of theplug. The upper end of the handle and the projecting end of the plug areprovided with openings adapted to register, and a pin 24 is insertedthrough the said openings so as to lock the handle to the plug wherebymovement of the handle, independently of the plug in any direction, willbe prevented. The upper end of the handle plays against a quadrant 25formed on the adjacent side of the angle cock body, and this quadrant isprovided at its opposite sides with the lugs 26 which constitute stopsto limit the movement of the handleand is also provided with thediverging grooves 27 disposed at a right angle to each other and adaptedto be engaged by a latch 28 carried by the handle so that the handlewill be held in either of its set positions. When the latch engages onerecess or groove, the air will be cut out and when the latch engages theother groove or recess, the air will be cut in, as will be readilyunderstood.

The latch 28 is seated within a tubular portion 29 of the handle, whichtubular portion extends outwardly from the upper end of the handle at aright angle thereto and has the main body or lever of the handledepending from its outer end. The outer end of the tubular portion orbarrel 29 is internally threaded to receive a cap 30 which has an outerangular end adapted to be engaged by a wrench or similar tool wheninserting or removing the cap and is also constructed with a rib orflange 31 which limits the inward movement of the cap by engaging theouter surface of the handle, as will be readily understood on referenceto Fig. 5. The latch 28 is mounted in the barrel 29 in advance of thecap 30 and comprises a stem 32, an annular disk or body 33 at one end ofsaid stem, and a locking tongue 34c projecting from the said disk orbody toward the open end of the barrel. The end of the locking tongue34: is tapered, as clearly shown in Fig. 7, to properly engage theinwardly converging walls of the grooves 27 and thereby avoid stickingin the grooves, while, at the same time, the handle will be efi'ectuallyheld in either of its adjusted positions. The tongue 3a is fiat, asclearly shown, and plays between the lugs or projections 35 formedwithin the barrel at the end thereof so that rotary movement of thelatch cannot occur and it Will be constantly maintained in properposition to enter either groove 27. The annular body or disk 33constitutes a stop to prevent ejection of the latch by engaging theinner sides of the lugs 35, and a spring 36 is coiled around the stem 32between the said body or disk 33 and the cap 30, as clearly shown inFig. 5, said spring tending by its expansion to project the latch sothat it will automatically engage either groove. When sufficient forceis applied to the lever portion of the handle to turn the same and theplug, the tapered end of the latch, co-acting with the converging facesor walls of the grooves, will permit the latch to automatically recedefrom the groove and compress the spring 36, but unless suflicient forceis applied to the handle to turn the same laterally, the latch will holdthe handle in its set position and consequently accidental turning ofthe plug will be prevented.

The depending lever portion of the handle is provided at its lower endwith two openings 37 which receive pivot pins whereby the inner ends ofoperating rods are attached to the handle. These rods extend laterallyto opposite sides of the car and pass through suitable hangers. Byactuating the operating rods, the valve may be easily shifted and thelatch will hold it in its shifted positions.

The operation and advantages of my improved angle cock are believed tobe evident from the foregoing description, taken in connection with theaccompanying drawings, and detail mention of the same is deemedunnecessary.

By the use of my improvements, the necessity of the trainmen passingbetween the cars in order to operate the angle cocks is overcome so thatlife and limb will not be endangered and the cock may be easily operatedfrom either side of the car and will not be apt to freeze and stick inextreme weather.

What I claim is An angle cock for train-pipes comprising a tubular bodyhaving a vertically disposed portion, a tapered turning plug seatedhorizontally in said vertically disposed portion, means on the smallerend of said plug for turning the same, a socketed cap secured in theside of the body over the larger end of the plug, an opening throughsaid end of the plug establishing communication between the socketedportion of the cap and the bore ofaplug, anda drain passage in the wallof the body establishing communication between the socket of the cap andthe bore of the body below the plug.

In testimony whereof I aifix my signature in presence of two witnesses.
